"A little over a year ago Zahn put the Hydro H50 Liquid CPU Cooler through the paces and awarded it our Silver Seal of Approval based on its performance, price and installation procedure. It has since followed up on the original design with the release of the H70 which we will be taking a look at here today. The H70 features a lower profile water block / pump assembly, a thicker radiator and dual cooling fans, among other changes. These improvements sound great in theory but will they translate to real-world performance?"
